-(CCSprite *)spriteWithColor:(ccColor4F)bgColor textureSize:(float)textureSize {
// 1: Create new CCRenderTexture
CCRenderTexture *rt = [CCRenderTexture renderTextureWithWidth:textureSize height:textureSize];
// 2: Call CCRenderTexture:begin
[rt beginWithClear:bgColor.r g:bgColor.g b:bgColor.b a:bgColor.a];
// 3: Draw into the texture
// We'll add this later
// 4: Call CCRenderTexture:end
[rt end];
// 5: Create a new Sprite from the texture
return [CCSprite spriteWithTexture:rt.sprite.texture];
}
最后那个rt.sprite.texture如果用C++写，应该怎么改，谢谢大神啊
------解决方案--------------------
CCSprite::spriteWithTexture(rt->getSprite()->getTexture());
